the other. These were obtained by measuring the diameter of an iron sphere with several trials made by each member of the group using measuring devices such as the Foot Rule‚ the Vernier Caliper and the Micrometer Caliper. The group found out that in measuring‚ both the Vernier Caliper and the Micrometer Caliper are preferable to use for these can give more accurate measurements compared to what a Foot Rule can. The deviation‚ volume‚ mass and density of the iron sphere were also identified. 1.

Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count
